Embodiment 1
[0047] The dust suppressant for coal mine mainly includes the following components according to weight percentage: 0.05% octylphenol polyoxyethylene ether, 0.05% lauryl betaine, 99.789% water and 0.111% calcium chloride, and Control the calcium chloride containing 0.01 mole number in every dust lifting agent.
[0048] Such as image 3 Shown, above-mentioned dedusting agent can be applied in coal mine by following steps, it comprises the following steps:
[0049] a. Fully mix 0.05% octylphenol polyoxyethylene ether, 0.05% lauryl betaine, 99.789% water and 0.111% calcium chloride according to weight percentage, and control the content of each liter of mixed solution The calcium chloride of 0.01 moles makes dust suppressant, and dust suppressant is put into water tank 11;
[0050] b. When the working face in the coal mine is working, start the clean water pump 14, and simultaneously start the quantitative pump 12 through the linkage switch 15, and the quantitative pump 12 will ...

[0062] b. When the working face in the coal mine is working, start the clean water pump 14, and simultaneously start the quantitative pump 12 through the linkage switch 15, and the quantitative pump 12 will press th...
Embodiment 3
[0067] The difference between embodiment 3 and embodiment 2 is that the weight percent of each component is different, and the dust suppressant for coal mine is composed of the following components according to weight percent: 0.06% octylphenol polyoxyethylene ether, 0.06% Dodecyl betaine, 99.547% of water and 0.333% of calcium chloride, and controlled to contain 0.03 moles of calcium chloride per dust elevating agent.
[0068] Such as image 3 Shown, above-mentioned dedusting agent can be applied in the spray dedusting system of coal mine by following steps, and it comprises the following steps:
[0069] d. Fully mix 0.06% octylphenol polyoxyethylene ether, 0.06% lauryl betaine, 99.84% water and 0.333% calcium chloride according to the weight percentage, and control the content of each liter of mixed solution The calcium chloride of 0.03 moles makes the dust-reducing agent, and puts the dust-reducing agent into the water tank 11;
[0070] e. When the working face in the coa...
